   solutions.css
   Solutions Hub — inherits the cinematic blueprint design system
   from service-cloud.css but introduces unique components:
     - .hub-svg            hero constellation (8 solutions × 4 outcomes)
     - .ogrid / .ocard     outcome group cards
     - .solgrid / .scard   8 solution cards with per-card micro SVGs
     - .engmodel           Advisory + Implementation + Managed stack
     - .sectormx           solutions × industries fit matrix
   Self-contained per the existing per-page pattern.
